seekKeyFrame fails seeking to first frame #238

Open GoogleCodeExporter opened 8 years ago

In the following code, ret is never >=0 (ie successful seek) for 
entryNum==0:

for(int entryNum=0; entryNum < numEntries; entryNum++){
  indexEntry = stream.getIndexEntry(entryNum);
  if(indexEntry.isKeyFrame()){
    IVideoPicture picture = IVideoPicture.make(coder.getPixelType(),
    coder.getWidth(), coder.getHeight());
    int ret = container.seekKeyFrame(stream.getIndex(), -1,
        indexEntry.getTimeStamp(), stream.getDuration(), 0);

indexEntry.getTimeStamp()==-0.2002 for entryNum==0

I've tried all sorts of combinations for minTimeStamp parameter of 
seekKeyFrame, doesn't make any difference. I got around it for entryNum==0 
by simply decoding packets from the start of the stream till I have a full 
picture and it is a keyFrame.
